There are issue however:
1. IL2CPU modifications are needed (see the PR for the list of the PR of IL2CPU to merge to make this usable)
2. Some fix in IL2CPU seems to give problems with Dictionary (VMT problem again?)
3. Hashtable with valuetype as key doesn't work (ContainsKey() always return false)
- moved EncodingTest on Text subdir
- added ConsoleTest (not enabled by default)
- removed ASCIIEncodingImpl (it was not needed)
- Made plugs of Console better and added plugs for formatted versions
- Removed code to test Hashtable, Hashtable it will be a separate PR
